Additional Notes
Why is a standard HashMap not thread-safe?
Track: Java
Topic: Concurrency
Focus: Concurrent Collections
Java: Concurrent Collections
Answer
HashMap is not synchronized, leading to data corruption.
HashMap allows multiple threads to read and write without synchronization, which can lead to data corruption. For example, during a flash sale, concurrent updates to product stock in a HashMap could result in incorrect inventory counts.
